🇩🇰 The best dictionaries for learning Danish

Run jointly by the Danish Language Council and the Society for Danish Language and Literature, sproget.dk collects usage articles, spelling rules and thousands of answered questions about Danish, plus links to the official reference works. When you need a defensible answer about commas, compound words or ligge/lægge, this is where it lives. Everything is in Danish and aimed at native speakers, so it is only usable from roughly B1 up.

Published by the Society for Danish Language and Literature, DDO covers Danish from 1950 onward and is updated continuously, with pronunciation recordings, gender, inflection tables, real usage examples and idioms on almost every entry. For a learner the audio and the en/et marking alone justify making it your default lookup. It is Danish-to-Danish only, so beginners will still need a bilingual dictionary alongside it.

This is the book Danish spelling rules are officially defined by, covering orthography, inflection and the comma rules, and it is free on the web. If you are writing Danish that will be marked — exams, applications, work email — settle disagreements here rather than by searching. It is a norm reference, not a learning resource: no definitions, no examples, no English.

ODS documents older Danish with full citations, which is what you need once you start reading Blicher, Pontoppidan or anything printed before the war and hit words DDO no longer carries. Purely a reference for advanced readers and anyone curious about how the language moved. Entries are written in older Danish themselves, so it is unusable below a solid C1.

Over 100 language editions; the English edition alone has millions of entries covering hundreds of languages, with IPA, declension and conjugation tables, etymologies and usage notes that commercial apps usually paywall. The etymology sections are quietly one of the best vocabulary-retention tools available. Being crowd-sourced, coverage is uneven and rare entries can be wrong — cross-check anything unusual against a native-language dictionary.

Around 6 million words recorded by native speakers across 400+ languages, usually with several accents per word so you can hear regional variation. Free to search on the site; the paid tiers are aimed at API users and bulk audio downloads. Indispensable for names, place names and anything a TTS voice would mangle — many learners wire it directly into Anki for card audio.
